Subject: r8152: fix writing USB_BP2_EN
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=e003a89219493ed1fa57a794d3ee22d50c424ebd;p=linux-block.git

r8152: fix writing USB_BP2_EN

[ Upstream commit a876a33d2a1102f99fc782fefb784f4dd4841d8c ]

The register of USB_BP2_EN is 16 bits, so we should use
ocp_write_word(), not ocp_write_byte().

Fixes: 9370f2d05a2a ("support request_firmware for RTL8153")
